Missouri splits heavy-truck registration between two agencies: the Department of Revenue’s contracted license offices handle intrastate titling and plates, while MoDOT Motor Carrier Services runs everything interstate — IRP, IFTA, and operating credentials — through its Carrier Express portal.
Two things make Missouri paperwork distinctive: a renewal calendar with four staggered quarters and split deadlines, and a statutory double-gate that demands your federal tax proof and your county property tax receipt before any plate is issued.
What MoDOT Carrier Express handles
Carrier Express is the online home for Missouri IRP accounts: new applications, renewals, supplements, and payments, backed by Motor Carrier Services at 830 MoDOT Drive, Jefferson City (1-866-831-6277 or 573-751-7100, contactmcs@modot.mo.gov). Title work still happens at a Department of Revenue motor vehicle office — MoDOT will not accept assigned (signed-over) titles, salvage titles, or bills of sale; the truck must be titled in the registrant’s own name first.
Four quarters, two deadlines each
Missouri staggers IRP into four registration periods, with plates expiring December 31, March 31, June 30, or September 30 — and each has two deadlines. The renewal application is due three months before your plate expires; payment is due one month before. Filing late costs $100; paying late costs $50 per power unit (up to $150).
MoDOT also holds renewals until IFTA and UCR are current, so the 2290 is one item on a longer clean-file checklist.
The 2290 proof MoDOT accepts
For every power unit licensed at 55,000 pounds or more, MoDOT’s acceptable-documents list names three formats:
- A copy of the electronic filing showing all VINs and the IRS e-file watermark — what e-filers receive within minutes
- A Schedule 1 stamped by the IRS
- A front-and-back copy of the cancelled check together with the Schedule 1 listing the VINs — with the bank account number blacked out (MoDOT says so explicitly)
Missouri publishes its own written grace rule: no proof of payment is required for newly purchased vehicles if the purchase date is within the last 60 days. The federal filing deadline still runs, so the watermarked Schedule 1 should exist long before day 60.
The second gate: the county property tax receipt
Missouri statute (RSMo 301.025) bars any registration unless the application comes with a paid personal property tax receipt for the preceding year showing no delinquencies. For IRP, the receipt must come from the county collector where the carrier is based and be in the titled owner’s or registrant’s name; a county-issued waiver or a no-Missouri-distance affidavit can substitute. New IRP accounts also need three proofs of Missouri residency at a physical address — PO boxes are not accepted.
